Ammonit: Überlebte drei Massenaussterben, verpasste das vierte um 66 Millionen Jahre

von/ durch Laura Konst

Ammoniten überlebten 335 Millionen Jahre und überdauerten drei separate Massenaussterben, die das Leben auf der Erde neu gestalteten. Sie verschwanden im vierten: dem Asteroideneinschlag vor 66 Millionen Jahren, der auch die nicht-aviären Dinosaurier beendete. Jedes existierende Ammonitenfossil ist die erhaltene Schale eines Tieres aus dieser verschwundenen Welt, das durch Millionen von Jahren geologischer Prozesse von Aragonit zu Stein verwandelt wurde.
